摘　　要：采用合金法和扩散偶法,通过电子探针显微分析(electron probe micro-analysis,EPMA)和X射线衍射(X-ray diffraction,XRD)等方法测定了Co-Mo-Re三元系1200℃等温截面的相平衡关系。结果表明:1200℃等温截面由9个单相区、16个两相区和8个三相区组成,还发现了两个新的三元化合物τ1和τ2。Phase equilibria of 1200℃isothermal section of Co-Mo-Re ternary system were investigated via alloy sampling and diffusion couple assisted with electron probe micro-analysis and X-ray diffraction methods.The results showed that 1200℃isothermal section consisted of 9 single-phase regions,15 two-phase regions and 8 three-phase regions,and two new ternary compounds,namedτ1 andτ2,were discovered.
